I thought linux was low on resources?
Can anyone tell me why 94% of my memory is in use?
As you can tell from my top output, I don't have much running - fvwm2 as the windowmanager, an opera 7 session, and thats about it.
In Windows XP, I can have 10x that running and still keep memory usage under 40%. what gives?
To make matters worse, the %MEM column of top hardly adds up to 94%
Code:
Tasks: 51 total, 3 running, 47 sleeping, 1 stopped, 0 zombie
Cpu(s): 11.3% user, 3.3% system, 0.0% nice, 85.4% idle
